T4,G2,G3,G4 Valve Guide - 2.8 VR6 (AES)

This replacement valve guide is designed for 2.8 VR6 engines, most notably the AES engine code fitted to the VW T4 Transporter. It is suitable for both inlet and exhaust valves, making it a versatile and essential component during cylinder head overhauls, valve seat work, or full engine rebuilds.

The valve guide ensures the valve stem remains perfectly aligned as the valve opens and closes at high speed. Correct alignment is vital for maintaining compression, preventing premature valve seat wear, and controlling oil flow to the valve stem seals. Worn valve guides are a common cause of blue exhaust smoke, high oil consumption, noisy valve operation, and loss of efficiency—particularly on higher-mileage VR6 engines.

Manufactured to precise tolerances, this guide is a press-fit replacement designed to restore factory-style valve control and long-term reliability.
